可能原因包括：驅(qū)動(dòng)未安裝、數(shù)據(jù)線問(wèn)題、手機(jī)USB調(diào)試未正確開(kāi)啟、電腦端權(quán)限未授予或系統(tǒng)設(shè)置限制。建議檢查數(shù)據(jù)線是否正常，確認(rèn)驅(qū)動(dòng)安裝，確保手機(jī)授權(quán)彈窗已允許，嘗試更換接口或數(shù)據(jù)線測(cè)試連接穩(wěn)定性。

可能原因有：數(shù)據(jù)線損壞，嘗試換根線；電腦未安裝合適驅(qū)動(dòng)，需安裝對(duì)應(yīng)手機(jī)驅(qū)動(dòng)；手機(jī)設(shè)置中選擇的USB連接模式不正確，可切換模式再試。

可能原因有：數(shù)據(jù)線損壞、電腦未安裝手機(jī)驅(qū)動(dòng)、手機(jī)USB接口接觸不良、電腦USB接口故障、手機(jī)設(shè)置里有其他限制（如安全軟件阻止）等。

你只要到手機(jī)里面設(shè)置-程序-安裝與調(diào)試-打開(kāi)USB調(diào)試，必須找到USB調(diào)試打開(kāi)然后系統(tǒng)自動(dòng)安裝驅(qū)動(dòng)，安裝完畢后就可以了。

如果你的手機(jī)是插在電腦前邊的有可能是你電腦前邊插口電壓不穩(wěn)的原因，如果是的話試著插在電腦后邊。或者你的電腦沒(méi)有你手機(jī)的驅(qū)動(dòng).....

驅(qū)動(dòng)重裝下看看

你好！
進(jìn)入“設(shè)置”——“全部設(shè)置”界面——“關(guān)于手機(jī)”——連續(xù)快速點(diǎn)擊“android版本”5次，即可打開(kāi)“開(kāi)發(fā)者選項(xiàng)”，進(jìn)入“開(kāi)發(fā)者選項(xiàng)”，就可找到usb調(diào)試了。
希望能幫到你，望采納！

這是電腦中還缺少手機(jī)驅(qū)動(dòng)程序所致，解決辦法是：
1、必須要先打開(kāi)“USB調(diào)試”；
2、分別在電腦和手機(jī)下載安裝 豌 豆 莢 軟件，用USB線將手機(jī)與電腦連接，電腦中的 豌 豆 莢會(huì)自動(dòng)在網(wǎng)上搜索并安裝適合你手機(jī)的驅(qū)動(dòng)，在手機(jī)彈出的USB選項(xiàng)中選手第二項(xiàng)“媒體設(shè)備（MTP）”，確認(rèn)與電腦連接了。安裝豌 豆 莢以后，可選擇Wifi連接方式，可通過(guò)wiFi實(shí)現(xiàn)無(wú)線連接，不需USB線。
